For anyone who goes online, it’s impossible to hack-proof yourself, but not impossible to make a hacker’s job extremely difficult. Here are three things to almost hack-proof yourself.
Two-factor authentication. Imagine a hacker, who has your password, trying to get into your account upon learning he must enter a unique code that’s sent to your smartphone. He doesn’t have your smartphone. So he’s at a dead-end.
The two-factor authentication means you’ll get a text message containing a six-digit number that’s required to log into your account from someplace in public or elsewhere. This will surely make a hacker quickly give up. You should use banks and e-mail providers that offer two-factor. Two factor in various forms is available on Gmail, iCloud, PayPal, Twitter, Facebook and many other sites.
Don’t recycle passwords. If the service for one of your accounts gets hacked, the exposed passwords will end up in the hands of hackers, who will invariably try those passwords on other sites. If you use this same password for your banker, medical health plan and Facebook…that’s three more places your private information will be invaded.
And in line with this concept of never reusing passwords, don’t make your multiple passwords sound schemed (e.g., Corrie1979, Corry1979, Corree1979) for your various accounts, because a hacker’s penetration tools may figure them out.
Use a password manager. With a password manager, you’ll no longer be able to claim not being able to remember passwords or “figure out” how to create a strong password as excuses for having weak, highly crackable passwords. You’ll only need to know the master password. All of your other passwords will be encrypted, penetrable only with the master password.
A password manager will generate strong passwords for you as well as conduct an audit of your existing passwords.
